## What is Audio RTA?

See the live sound spectrum, find frequency peaks and test your speakers with a practical audio toolkit on your phone.

For musicians, sound technicians and installers working with PA systems, studios, instruments and car audio. Use the microphone spectrum as a visual aid when checking sound; the app does not automatically equalize your system.

Free basic tools:
• Real-time microphone RTA/FFT spectrum
• Approximate dB level meter
• Frequency generator from 20 Hz to 20 kHz
• Subwoofer and stereo channel tests
• White noise for general testing

Audio Tools Pro is a one-time purchase for lifetime access to advanced tools: waterfall/spectrogram, third-octave bands, manual dB offset, PNG/CSV exports, pink noise and advanced waveforms and sweeps. Access stays linked to your store account.

Measurements depend on your device microphone and hardware. Manual dB offset aligns readings to a reference meter; it does not provide certified calibration. Use low volume to protect hearing and equipment.

The app does not replace a certified sound-level meter or measure calibrated loudspeaker frequency response. Audio analysis runs on your device; purchases require a connection. The store shows the current Pro price.
